IMPROVEMENT IN METALLIC HUBS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, JOHN OLIPHANT, of Springhill Furnace, Fayette county, and State of' Pennsylvania,

have invented a new and useful Improvement in Metallic Hubs for Wheels; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to thean'ncxed drawings, and the letters of reference marked thereon, in which- I V Figure l is a perspective view of the hub.

Figure 2, a longitudinal section through the liner: x of fig. 1. Figure 3 is a perspective view of one of the sections removedfrom fig. 1; Like letters refer to like parts in all the figures. i i v The nature of my invention consists in constructing metallic hubs in such a manner that one or more of the spokes may be removed from the wheel, when broken or ihju'red, and replaced by new ones, in as perfect and substantial a manner as by the usual meth'oihwithout removing the tire or felloes' or displacing any of the other spokes, and also in applying to the hub removable boxes, which may be driven from the hub and their places supplied with new ones, when the old boxes are badly worn 'To enable others skilled in the art to,makeand use my invention, I will proceed to describeits construction and operation. I

A is the tube or body of the huh; B B are the boxes which provide bearings for-the axle, and being made separate from the tube A, can be removed when they become worn, and replaced by new ones, the outer surface of the boxes 1313 being made conicah'so as to provide means of their being-driven in the tube A in a rigid and secure manner.

C C are mud-bands, which are heated and shrunk on the tube A, which strengthen it and protects it from being broken, either by the driving in of the boxes B B or from other causes; I

D D are bolts, which pass through themud-bands C C, the tube A, and into the boxes B B, and prevent the mud-bands and boxes from working loose. 1 t

'E isa flange, with the radial'p'artiticns F F F cast or welded on the tube A.

T-T are bevels on the flange E, to give the wheel the proper dish. 7

G G G are spaces for the spokes, the bottoms, H H, of which are bevelled, to force the spokes from the centre of the hub.

I is a disk divided into sectors, J J J, formiug a cap for each spoke, which are securely bound in the hub by the caps J J J!, being retained immovable in their places by the annular groove Iiin the tube A, the projections M M M fitting into the recesses N Niin the caps J J J, and the bolts 0 O O passing through the caps J J JC the spokes and the flangeE binding the whole firmly together.

Should it become necessary to remove a spoke from the wheel, unscrew the nut or one of the bolts 0 which passes through the spoke to be taken out, and 'the bolt, and one of the caps J througlvwhich the bolt passes, can easily be removed, as shown in fig. 3. The spoke is then driven frourthe hub and detached from the felloe. The new spoke can then be placed inthe wheel, by first inserting the tenon or the small end of the spoke into the mortise in the felloe, and driving the hub-end of the spoke into one of: the spaces G in the hub, the bevel H forcing the spoke out firmly against the felloe, which also tightens the tire. Should the bevels H H be insufiicient to force the spokes out the desired distance, their inclination can beincreased, and thebevels extended on the tube A, as shown n red outline at n n in fig. 2, till the required distance is obtained. The hole througlgwhich bolt 0 is to pass is now bored through the spoke, and the cap J is replaced, by first inserting the smaller end in the groove L, and passing the bolt 0' through cap J, the spoke, and flange E. The nut is now screwed on the bolt 0', .and the spoke is securely bound in the wheel, the cap J being retained immovable in its place by the groove L, projections M M, and the bolt 0. i

.This device has been used and thoroughly tested by the inventor on furnace-wagons, which are required to withstand theroughest usage, and after six or eight months"consta nt use, are in as good conditionas'when first put together, thus proving'them to be a most useful and valuable invention. 1 Agreat advantage, in addition to their strength and durability, is the facility with which they are repaired by any one having the slightest mechanical knowledge, thus rendering the expense and trouble incurred by having the wheel taken apart and repaired by a regular mechanic unnecessary. I

Having thus described the construction and operation of my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combinationof the disk I, divided into'the sectors or eaps J J J", the annular groove L, the projections M M M and the recesses N N N, as and for the purpose set forth. 2. The bevels H H and T T, as and for the purpose set forth. 7 3. The combination of the boxes B B, tube A, mud-bands C G, and screws D D, substantially as and for the purpose specified. 1
